Description

Technical Field

[0001] This utility model belongs to the technical field of pigment production equipment, and in particular relates to a blown film filter press for the production of ultramarine pigment. Background Technology

[0002] Ultramarine purple pigment, a commonly used purple pigment, is widely used in industries such as coatings, inks, and plastics. In the production process of ultramarine purple pigment, the filter press process is a crucial step. Its main function is to separate the liquid from the solid pigment in the pigment slurry to obtain a pigment filter cake with the required water content. Due to its high filtration efficiency and relatively simple operation, blown film filter press has been used to some extent in the production of ultramarine purple pigment.

[0003] The existing utility model with authorization announcement number CN218280678U discloses a high-efficiency diaphragm filter press, including a base and a separation component. The first support and the second support are connected by two beams. A thrust plate is installed on the rear surface of the second support. A hydraulic component is installed on the front surface of the first support. A pressing plate is installed at one end of the hydraulic component. Several filter plates are placed on the top surface of the beams. Two support rods are connected to the upper ends of the first support and the second support.

[0004] The above technical solution involves installing a moving rod on the pressing plate, with a limit block on the moving rod. The limit block can drive the pulling plate to move, thereby causing the pulling plate to move the filter plate, allowing all the filter plates to separate at once, thus improving efficiency. However, in the above technical solution, the filter plate is directly installed on the outside of the main beam through the support block, allowing the filter plate to slide along the main beam. This makes it difficult to disassemble the filter plate and clean the pigment residue inside. Furthermore, it cannot automatically clean the pigment residue on both sides of the filter plate. After replacing the filter membrane or completing the filtration operation, cleaning becomes difficult, and the residual pigment not only causes waste but may also affect the quality of the next filtration operation.

[0005] Therefore, we propose a blown film filter press for the production of ultramarine pigment to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem of inconvenient cleaning of filter membranes in the prior art, and to propose a blown film filter press for the production of ultramarine pigment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A blown film filter press for ultramarine pigment production includes a filter press body. Two limiting grooves are formed on the upper surface of the filter press body. An electric slider is slidably connected inside each limiting groove. A support column is fixedly connected to the upper surface of each electric slider. A mounting frame is fixedly connected to the top of both support columns. An electric telescopic rod is fixedly connected to the inner wall of the mounting frame. A moving plate is fixedly connected to the telescopic end of the electric telescopic rod. Two cleaning brushes are fixedly connected to the bottom surface of the moving plate. Equally spaced mounting blocks are slidably connected inside the filter press body. Each mounting block has two mounting grooves and fixed threaded holes on its upper surface. Each set of mounting slots has a filter screen plate slidably connected inside, and a fixed top plate is fixedly connected to the upper surface of each set of filter screen plates. The two sides of one of the mounting blocks, the two sides of one of the fixed top plates, and the two sides of the filter screen plates that are far apart from each other are in contact with the cleaning ends of the two cleaning brush plates. The interior of each set of fixed top plates is threaded with mounting bolts. The bottom ends of the two sets of mounting bolts pass through the two sets of fixed top plates in sequence and are threadedly connected to the interior of the two sets of fixed threaded holes. The outer surface of each set of mounting bolts is fixedly connected with a retaining ring and a lifting plate. The bottom surfaces of the two sets of retaining rings are in contact with the upper surfaces of the two sets of fixed top plates.

[0009] Preferably, a material receiving pool is provided below the main body of the filter press, and an installation base plate is fixedly connected to the bottom surface of the material receiving pool.

[0010] Preferably, two first hydraulic cylinders are fixedly connected to the upper surface of the mounting base plate, and two connecting frames are fixedly connected to the upper surface of the filter press body. The telescopic ends of the two first hydraulic cylinders are respectively fixedly connected to the bottom surfaces of the two connecting frames.

[0011] Preferably, the inner wall of the filter press body is fixedly connected with second hydraulic cylinders arranged at equal intervals, and each of the second hydraulic cylinders has a push plate fixedly connected to its telescopic end.

[0012] Preferably, the inner wall of the filter press body is fixedly connected with equidistant guide rods, and one side of each mounting block is provided with equidistant guide holes, and several of the guide rods are slidably connected to the inside of two sets of guide holes.

[0013] Preferably, two telescopic springs are fixedly embedded on both sides of each mounting block, and a movable pressing plate is fixedly connected to the ends of the two sets of telescopic springs that are far apart from each other, and the sides of the two movable pressing plates that are close to each other are in contact.

[0014] Preferably, each of the two support columns has an extension reinforcing rod fixedly connected to one side of each other, and the ends of the two extension reinforcing rods are fixedly connected to the bottom surface of the mounting frame.

[0015] Preferably, the telescopic end of the electric telescopic rod is fixedly connected to a reinforcing ring, and the bottom surface of the reinforcing ring is fixedly connected to the upper surface of the movable plate.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] By configuring the filter press body, limiting slide groove, electric slider, support column, mounting frame, electric telescopic rod, moving plate, and cleaning brush plate, a limiting slide groove can be opened on the filter press body to allow the electric slider to slide inside. This facilitates the movement of the support column and mounting frame, allowing the moving plate and cleaning brush plate to move to both sides of the filter screen of the blown film filter press. The electric telescopic rod drives the moving plate and cleaning brush plate to move up and down to clean both sides of the filter screen. The mounting block, mounting groove, fixing threaded hole, filter screen, fixing top plate, mounting bolts, retaining ring, and lifting plate work together to easily attach the two filter screens to the mounting grooves on both sides of the mounting block via the fixing top plate. Tightening the mounting bolts installs the fixing top plate above the mounting block, facilitating the disassembly and assembly of the filter screens for cleaning and replacement, thus improving the pigment processing efficiency of the blown film filter press.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 A blown film filter press for the production of ultramarine pigment includes a filter press body 5. A material receiving pool 2 is provided below the filter press body 5. An installation base plate 1 is fixedly connected to the bottom surface of the material receiving pool 2. The material receiving pool 2 fixed on the installation base plate 1 is used to facilitate the collection of the finished product produced by the filter press process.

[0026] Two first hydraulic cylinders 3 are fixedly connected to the upper surface of the mounting base plate 1, and two connecting frames 4 are fixedly connected to the upper surface of the filter press body 5. The telescopic ends of the two first hydraulic cylinders 3 are fixedly connected to the bottom surfaces of the two connecting frames 4 respectively. By controlling the two first hydraulic cylinders 3, the two connecting frames 4 are driven to move up and down, thereby driving the filter press body 5 to move up and down, which facilitates the operation of the blown film filter press.

[0027] Two limiting grooves 6 are provided on the upper surface of the filter press body 5. An electric slider 7 is slidably connected inside each limiting groove 6. The electric slider 7 is an electrically controlled sliding slider structure that can be controlled to slide within the limiting groove 6. A support column 8 is fixedly connected to the upper surface of each electric slider 7. A mounting frame 9 is fixedly connected to the top of the two support columns 8. An extension reinforcing rod 10 is fixedly connected to the side of the two support columns 8 that is close to each other. The end of the two extension reinforcing rods 10 that is close to each other is fixedly connected to the bottom surface of the mounting frame 9. The extension reinforcing rods 10 are fixed between the support column 8 and the mounting frame 9 to improve the connection stability between the support column 8 and the mounting frame 9, thereby stably cleaning the filter structure of the blown film filter press.

[0028] An electric telescopic rod 11 is fixedly connected to the inner wall of the mounting bracket 9. A movable plate 12 is fixedly connected to the telescopic end of the electric telescopic rod 11. A reinforcing ring 14 is fixedly connected to the telescopic end of the electric telescopic rod 11. The bottom surface of the reinforcing ring 14 is fixedly connected to the upper surface of the movable plate 12. The reinforcing ring 14 is fixed at the connection between the telescopic end of the electric telescopic rod 11 and the movable plate 12, thereby improving the connection stability between the telescopic end of the electric telescopic rod 11 and the movable plate 12.

[0029] Two cleaning brush plates 13 are fixedly connected to the bottom surface of the movable plate 12. The filter press body 5 has equidistantly arranged mounting blocks 18 slidably connected inside. The inner wall of the filter press body 5 has equidistantly arranged second hydraulic cylinders 15 fixedly connected. Each second hydraulic cylinder 15 has a push plate 16 fixedly connected to its telescopic end. The multiple second hydraulic cylinders 15 fixed to the inner wall of the filter press body 5 provide power to drive the push plate 16 to move, so that the push plate 16 can push the mounting block 18 to slide inside the filter press body 5, so as to facilitate the filtration processing of ultramarine pigment raw materials between two mounting blocks 18.

[0030] The inner wall of the filter press body 5 is fixedly connected with equidistant guide rods 17. Each mounting block 18 has equidistant guide holes 19 on one side. Several guide rods 17 are slidably connected to the inside of two sets of guide holes 19. By sliding the guide rods 17 inside the guide holes 19, the sliding stability of the mounting block 18 in the filter press body 5 can be improved, thereby enabling stable filtration processing of ultramarine pigment raw materials.

[0031] Each mounting block 18 has two mounting grooves 22 and fixing threaded holes 23 on its upper surface. A filter screen plate 24 is slidably connected inside each mounting groove 22. A fixing top plate 25 is fixedly connected to the upper surface of each filter screen plate 24. Two sides of one mounting block 18, two sides of one fixing top plate 25, and one side of two filter screen plates 24 that are far apart from each other contact the cleaning ends of two cleaning brush plates 13. Mounting bolts 26 are threadedly connected inside each fixing top plate 25. The bottom ends of the two sets of mounting bolts 26 pass through the two sets of fixing top plates 25 and are threadedly connected to the inner surfaces of the two sets of fixing threaded holes 23. The outer surface of each set of mounting bolts 26 is fixedly connected to... The mounting block 18 is equipped with retaining rings 27 and lifting plates 28. The bottom surfaces of the two sets of retaining rings 27 are in contact with the upper surfaces of the two sets of fixed top plates 25 respectively. Two telescopic springs 20 are fixedly embedded on both sides of each mounting block 18. The ends of the two sets of telescopic springs 20 that are far apart from each other are fixedly connected to movable extrusion plates 21. The sides of the two movable extrusion plates 21 that are close to each other are in contact. By setting two telescopic springs 20 and movable extrusion plates 21 between the two mounting blocks 18, the pressure can be released after the filter press is completed, and the elastic force in the telescopic springs 20 will be released, so that the two mounting blocks 18 can move away from each other, and the processed raw material between the two mounting blocks 18 will fall into the material receiving pool 2 for collection.

[0032] The working principle of this utility model is as follows: In use, firstly, connect the first hydraulic cylinder 3, electric slider 7, electric telescopic rod 11, and second hydraulic cylinder 15 to the power supply. When using this blown film filter press to process ultramarine pigment, first manually place the blown film filter press on a horizontal surface. The material receiving pool 2 located under the filter press body 5 allows the mounting base 1, whose bottom surface is fixed, to contact the upper surface of the horizontal surface, thus ensuring the blown film filter press is stably positioned on a horizontal surface. The ultramarine pigment is processed by pressure filtration. The two filter screens 24 are manually inserted into the mounting grooves 22 on both sides of the mounting block 18 until the filter screens 24 are inserted into the bottom of the mounting grooves 22. The lifting plate 28 is manually twisted so that the mounting bolts 26 can pass through the fixed top plate 25 and connect with the fixed threaded hole 23 until the bottom surface of the retaining ring 27 contacts the upper surface of the fixed top plate 25. This makes it easy to install the two filter screens 24 on both sides of the mounting block 18.

[0033] Next, by controlling the power supply of the hydraulic system valve of the first hydraulic cylinder 3, the telescopic end of the first hydraulic cylinder 3 can retract downward, which can move the filter press body 5 fixed on the bottom surface of the connecting frame 4 downward until the multiple mounting blocks 18 can contact the inner bottom wall of the material receiving pool 2. At this time, the raw material for processing ultramarine pigment is manually transported between the two mounting blocks 18 and the filter screen plate 24. Then, by controlling the power supply of the hydraulic system valve of the multiple second hydraulic cylinders 15, the second hydraulic cylinders 15 can drive the push plate 16 to move, which in turn pushes the mounting blocks 18 and the filter screen plate 24. Since two sets of mounting grooves 22 and moving extrusion plates 21 are set between the two mounting blocks 18, the two mounting blocks 18 can be brought closer together, and the telescopic spring 20 can be compressed into the mounting blocks 18, thereby squeezing and filtering the raw material between the two mounting blocks 18 and the filter screen plate 24. The filtered juice falls into the material receiving pool 2 for collection and is transported to the outside through pipeline.

[0034] When it is necessary to clean the raw material between the two filter screen plates 24, the second hydraulic cylinder 15 is controlled to prevent the multiple mounting blocks 18 from being squeezed, and the tension spring 20 is released, allowing the processed raw material between the two mounting blocks 18 to fall. The electric slider 7 is controlled to slide within the limiting groove 6, so that the support column 8 and the mounting frame 9, along with the two cleaning brushes 13, can move to both sides of the mounting block 18. The electric telescopic rod 11 is used to facilitate the downward movement of the two cleaning brushes 13, so that the cleaning brushes 13 can clean both sides of the two filter screen plates 24. Repeating the above steps allows the filter screen plates 24 to be disassembled for cleaning and replacement.
